They've been bad for a while, and have only gotten worse. Yesterday pretty much everyone in the server had ping over 300 for a few seconds, then went away. Poponfu is aware, but I don't know if anything will ever be done. That, and the respawn bug makes for a bad experience (monit plz?).
I had noticed this too starting maybe two months ago when things got past 7v7. I have a ping plotter myself showing some serious loss/spikes when it gets to fragnet. I will write them tomorrow and change hosts if they do not get back to me / tell me there is nothing they can do. Not too long ago I had seen a 10 v 10 that went smoothly and thought maybe fragnet had resolved this on their end, apologies.
I've updated the IP in the diagnosing network related issues thread. If you've done pingplotter reports to hotswap.legionsoverdrive.com - then you'll probably want to do them again.
I blame the person who stole the name Hotswap for a game server which isn't on the server called hotswap.
